Extended Beta - Flash Player NPAPI for Linux
Linux users have access to both NPAPI and PPAPI versions of Flash Player. However, for the last four years, the NPAPI version has been held at 11.2 and regularly updated with only security fixes while the PPAPI version (used in Chrome and Chromium based browsers), is in line with the standard Windows and Mac releases.
Today we are updating the beta channel with Linux NPAPI Flash Player by moving it forward and in sync with the modern release branch (currently version 23). We have done this significant change to improve security and provide additional mitigation to the Linux community.
In the past, we communicated that NPAPI Linux releases would stop in 2017. However, this is no longer the case, and once we have performed sufficient testing and received community feedback, we will release both NPAPI and PPAPI Linux with their major version numbers in sync and on a regular basis.
Because this change is primarily a security initiative, some features (like GPU 3D acceleration and premium video DRM) will not be fully implemented.
If you require this functionality, we recommend that you use the PPAPI version of Flash Player. That said, we believe that the new NPAPI build represents a significant step forward in functionality, stability, and security and look forward to hearing your feedback.
Currently we are distributing 32 and 64 bit binaries only, we will package these in proper installers after testing and feedback. Users should manually back-up their existing Flash Player plugin file from the appropriate system plug-in folder and copy the new binaries into place to use them.
so far we can see only 1 known issue
